Problems solved by technology
[0003] Although the above-mentioned conventional light-receiving component detection device can test the photoelectric characteristics of the light-receiving component, but because the light source is irradiated, it is limited by the light irradiation situation of the light source module, so the light source module must be installed with the light-receiving component. Only by forming a longer distance can the light source module have the effect of simulating parallel light when irradiating, which causes problems such as setting the light irradiation distance of the light source module is too far and the light irradiation position is not easy to align.
And because the light irradiation distance is too far, the intensity of the light source will attenuate seriously, and most of the light sources will not be able to concentrate on the light-receiving components. Unless the intensity of the light source is greatly increased, the test work will be difficult to implement; and in order to cooperate with the light source module In light irradiation and to achieve the effect of simulating parallel light, a considerable space must be used between the whole set of light-receiving component detection device and the light-receiving component to be tested, thus resulting in an increase in the cost of the testing process
[0004] Therefore, the conventional light-receiving component detection device cannot meet the needs of actual use

The invention provides a lens cone type detection device for a light receiving component by using a Fresnel lens to focus. The lens cone type detection device comprises a light source, a first Fresnel lens, a second Fresnel lens, a light receiving component and a lens cone, wherein the first Fresnel lens and the second Fresnel lens are arranged in the lens cone in parallel. Thus, the light source penetrates through the first Fresnel lens to emit a parallel light source onto the second Fresnel lens, and centrally focuses and irradiates the light receiving component through the second Fresnel lens to achieve the effect of effectively testing various photoelectric characteristics of the light receiving component.
Description
【Technical field】 [0001] The present invention relates to a lens barrel-type light-receiving component detection device focused by a Freund's lens, especially a device that utilizes a lens barrel and a Freund's lens, which can irradiate a light source on the light-receiving component in a concentrated manner to achieve Effectively test the photoelectric characteristics of light-receiving components. 【Background technique】 [0002] The general conventional light-receiving component detection device usually consists of a light-receiving component and a light source module arranged on one side of the corresponding light-receiving component at an appropriate distance; the light source can be adjusted by adjusting the distance between the light-receiving component and the light source module. The parallel light emitted by the module is irradiated on the light-receiving component to achieve the effect of testing the photoelectric characteristics of the light-receiving component. ...
